Classes and Class Hierarchies in C++ - Essay Example

? es and Hierarchies in C++ Explanation of the Concepts i. es A is a data structure in programming that enables the programmer to separate data types that are specific to a particular program. In C ++, programmers use classes to define the data structure as well as functions which operate in the data structures. A class defines objects belonging to one category. A sample class “Employee” is initiated as shown below: #include #include using namespace std; class Employee { Public: int Eage; string Ename; }; ii. Object Instantiation Object instantiation is the creation of an object, that is, the realization of a specific item of a class. It is an creation of objects with similar attributes (Malik, 2012). For example, the class called “Employees” can have objects (instances) of the class "Employees" for "Sam" and "Aristotle". Classes have instances for every data type, known as objects. An example of a C ++ program implementing a class (Employee) and its object is shown below: #include #include using namespace std; class Employee { Public: int Eage; string Ename; }; int main() { Employee a, n; a.Ename = "Sam"; n.Ename = "Aristole"; a.Eage = 33; n.Eage = 27; cout Read More
